Argonne Site Access

Argonne National Laboratory is a controlled-access facility. You will need a visitor’s pass or a user badge to enter the Argonne campus.

You must notify us of your visit in advance. When you arrive, you will be asked to present your identification documents, and then you will be given your pass or badge. You can then come and go freely during the period your pass or badge is valid. You must wear your pass or badge visibly at all times while on site. Do not wear your badge while offsite and never permit your badge to be photographed or filmed.
